SASH-FASTENER.

SPECIFICATION formingpart of Letters Patent No. 228,729, dated June 15, 1880. Application filed April 2'7, 1880. (No model.)

To all whom it may concern Be it known that I, LORENZO D. GLEAVE- LAND, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Sash-Fasteners, of which the following is a specification, reference being had to the accompanying drawings, illustrating the improvement, in which Figure 1. is a side elevation of my improved lock with the face-plate removed, more clearly to show the working parts, the same being applied to a sash, which is represented as being locked to the window-frame. Fig. 2 is the same view, only the bolt and other parts are in position as when the sash is unlocked. Fig. 3 is aperspective view of the exterior of the lock.

The object ofthe present invention is to provide more secure means for locking sash to window-frames.

The nature of the invention consists of a pcculiarly-formed bolt which is operated by a cam-lever in a suitable case, a hinged stop being employed to close the slot in the case in which the cam-lever operates, and to lock the cam-lever, so that the jarring of the sash or persons coming in contact with the lock will notdetach the bolt from the window-frame. The hinged stop also excludes dust from the working parts of the look inside of the case, as the whole is to be hereinafter fully described and shown.

L L represent the back and M the front plate of the lock-case, and L N represent the upper and lower plates thereof.

A is the bolt proper, and G is the bolt-stock,

which is guided in its movement by the plates L N, the wings B B of the stock (3 being constructed and fitted in the case for that purpose.

The wing B is provided with an upward projection, I, which operates between projections J D on the cam lever K, so that when said lever is brought down, as at Fig. l, the bolt A will be forced out at the end of the case and into thejamb-casing or other mechanism as a catch, and so that when the lever is raised up,

as shown at Fig. 2, the bolt will be drawn into the case.

The cam-lever K is pivoted to the case at S by a pin cast solid to the case M, and a shoulder is formed on it a little above the lever, so that the removable back plate may be riveted to it without clamping the lever K.

To lock the cam-lever K after the bolt A has been thrust out, a stop, F, is hinged to the corner of the case, and it is constructed. to cover the slot in the end of the case in which the cam-lever K operates, and its lower end engages a suitable bearing, E, on said lever. A nib or projection, H, on the top of the stop F is operated by the thumb to release the stop from the lever.

Figs. 1 and 2 represent right-hand locks attached to sash P T, and Fig. 3 represents a left-hand lock.

I claim and desire to secure by Letters Patent of the United States- The bolt A, constructed with the two-winged stock B B O and projection I, in combination with the cam -lever K, constructed with the projections J D, and the stop F, for closing the slot in the case and locking the cam-lever K, as and for the purpose set forth.
